What is the power level that you CAN use unlicensed?

Remember when RadioFree Allston was broadcasting on AM from Kenmore Square?

When they finally got their wattage under a legal limit, I seem to recall as
long as RFA was under 100 watts they were considered legal.

In Haverhill, web/streaming station WHAV.net is broadcasting on 1640AM (from
what I understan unlicensed and legal).

How many watts is that that they can stay on the legal side of the line?
